MOWI NG- MACHINE.

SPECIFICATION forming part of Letters Patent No. 392,658, dated November13, 1888.

Application filed J nnuary 3, 1887. Serial No. 223,179. (No model.)

ToaZZ whom it may concern:

Be it known that I, WILLIAM BAYLEY, of Springfield, in the county ofClark and State of Ohio, have invented a new and ImprovedMowing-Machine, of which the following is such a full, clear, and exactdescription as will enable any person skilled in the art to which itapplies to construct and use the same, reference being had to theaccompanying drawings, forming a part of this specification.

My invention relates to mowing-machines in general and particularly tothat class of machines commonly known as two-wheeled chain-drive-gearmachines, and is in the nature of improvements upon the usual form,arrangement, and construction of such machines.

The objects of my invention are to so con struct a mowing-machine thatby peculiarlyjointed connections the cutting apparatus may be raised toa vertical position, the inner end thereof rise and fall, the outer endrise and fall, the points of the fingers or guards tilt up or down tofollow the undulations of the ground over which it passes, all theseoperations being accomplished while the machine is running. Theseobjects are successfully accomplished by means of the deviceshereinafter described, and illustrated in the drawings hereuntoattached.

In the drawings, Figure 1 is a side elevation of the complete machine.Fig. 2 is a plan of the machine, omitting the elevating and tiltinglevers. Fig. 3 is a vertical section through the main shaft, main frame,and master-wheels, showing the device for throwing the machine into andout of gear. Fig. 4 is a side elevation, and Fig. 5 is an end elevation,of the shipping-lever by which the machineis thrown into and out ofgear. Fig. 6 is a partial side elevation showing the device for tiltingthe cutting apparatus. Fig. 7 is a partial side elevation showing thedevice for raising and lowering the inner end of the cutting apparatus.Fig. 8 is a partial side elevation showing the device for elevating anddepressing the outer end of the cutting apparatus. Fig. 9 is across-section through the drafttongue and sliding whiffletree-bracket.Fig. 10 is a perspective view of the inner shoe and the bracket to whichit is pivoted. Fig. 11

. shaft, gear-case, &c., on a line with the crankshaft. Fig. 14 is aperspective view of the supportingbar. Fig. 15 is a perspective view ofthe drag-bar; and Fig. 16 is a side elevation of the sprocket-wheel,sprocket-pinion, and chain-tightening device.

Similar letters refer to like parts in the several views.

A is the main frame, consisting of a long pipe box or tube of castmetal, through which the main shaft b passes loosely. At the rear sideof the frame A and near its center is formed the seat-spring bracket a,to which is attached the seat-spring a, supporting the drivers seat A".At the front side of the main frame and near one end is formed the lugor car a to which is pivoted the supportingbar 0, and another lug, a, towhich is pivoted the diagonal brace D, While the draft-tongue T is fixedto the bracket a also formed on the front side of the main frame A. Uponthe outer ends of the main shaft 1) are pivoted or journaled the maindriving and supporting wheels 13 and 13*, which are provided with thebacking-ratchets N, which, during the forward movement of themachine,are'eng aged by the usual pawls, b pivoted in the plates b and bfixed to the main shaft in the usual manner.

Loosely fitted upon the main shaft is the sprocket-wheel E, upon one endof whose hub is formed the half-clutch e, which engages the half-clutchc on the backing ratchet-plate b, as hereinafter described. A portion ofthe hub of the sprocket-wheel E is recessed in the form of a sleeve andfits over a portion of the pipe-box of the main frame A, which has agroove formed in it, the sprocket-wheel E being held in place by the pin6 in the sprocket-wheel E, which enters said groove,

as shown in Fig. 3.

Upon the backing ratchet-plate b is formed a sleeve over which is fittedthe shipper-lever F, a collar, b, formed on the plate If, engaging aninwardly-projecting rim, f, formed on the lever F, preventing lateralmotion of the latter in relation to the plate I). Formed in the lever Fis the cam-slotf", which is engaged by the hook f, which is fixed to themain frame by passing through a lug, a, formed thereon. The relativeposition, therefore, of the main frame to the plate I) is controlled bythe shipper-lever F, and as the sprocketwheel E is carried by the mainframeindependent of the main shaft or the backingplate I) and itshaltcluteh c, it follows that by swinging the shipper-lever F back orforward the main frame and sprocket-wheel E will be moved laterally tothe position shown by dotted lines in Fig. 3 and the machine thrown intoand out of gear'17. 0., started and stopped-as may be desired, thespring pin f" in the shipper F engaging slight slots (not shown) in themain frame to hold the shipper in either position.

The lateral movement of the sprocket-wheel E in the act of being throwninto and out of gear is not sufficient to disturb the working relationof the drive-chain.

G is a casting forming a casing for the combined bevel-gear andsprocket-pinion J and bevel-pinion K, as well as a bracket to which theinner shoe, H, of the cutting apparatus is pivoted, and has formed uponit the projection y, to which is fixed the dragbar L, and alsoproperjournals for the crank-shaft M.

The diagonal brace D is pivoted to the main frame at a*, and projectsdiagonally downward and forward to the gear-casing G, where it is bentat such an angle as to make it parallel to the main shaft 1). At thispoint it is circular, and, passing through the supporting-bar O at c,Fig. 11, and the drag-bar L at Z, Fig. 15, it forms a pivot orjournal,upon which the bevelgear and sprocket-pinion J revolves, after which itpasses through the gear-easing G, and is perforated for the passage ofthe crank-shaft M, and confined to its place by a nut placed outside ofthe gear-easing G. The form, position, and relation of these parts areshown in detail in Figs. 11, 12, and 13, and in general in Figs. 1 and2.

The supporting-bar C is pivoted to the main frame at a and projectsforward and downward at right angles to the main shaft b, and is pivotedat c to the diagonal brace D, as described, the pivots at a and aserving to pivotally connect the cutting apparatus and its appendages tothe main frame, by which the former may be free to rise and fall withrespect to the latter.

It is obvious that the diagonal brace D and the supporting-bar 6 should,strictly speaking, be pivoted upon or around the main shaft 1) or thepipe-box of the main frame A, in order that the sprocket-pinion J mayalways maintain its proper position in relation to the largesprocket-wheel E on the main shaft; but by pivoting the diagonal brace Dand supporting-bar O to the cars a" and c, which centers or pivots aredirectly in line with the main shaft 0 and sprocket-pinion J and quitenear the main shaft, their positions are changed so slightly when thecutting apparatus is elevated and depressed that practically theirworking relations are not impaired.

The drag-bar L is fixed to the gear-casing G by bolts at g g and beingbraced by the brace-rod g and at its front end pivoted to thetilting-lever N,which in turn is pivoted to the whiffietree frame orplate Q, to which the whiffletrees are pivoted at d, which slides uponthe track 1*,fixed to the draft-tongue, as shown in Figs. 1 and 2. Bythis device the cutting apparatus is tiltedi. 0., the points of thefingers elevated or depressed (turning on the diagonal brace where itpasses through the bevel-gear as a center) by means of the tiltingleverN, which is held in any desired position by the latch a engagingproperly-formed depressions or notches in the segment-plate q, formingpart of the whiflletree-plate Q. This operation and the relation of theparts in the several positions are clearly shown in Fig. 6.

To the draft-tongue T is pivoted the foot lever 0, having aproperly-formed foot-piece at the top and the bottom end extended beyondits pivotal point and being connected to the supporting-bar O by thelink q. By this device the operator may with his foot press upon the topend ofthefoot-lever O and elevate the inner end of the cuttingapparatus, as shown in Fig. 7, the whiflletree-frarne Q sliding upon thetrack P as necessary, and the catch-lever (f, pivoted to thedrafttongue,serving to hold the foot-lever 0 whenever desired, thespring q throwing the catch-lever q" forward, so as to engage thefoot-lever 0 whenever it is depressed.

The inner shoe of the cutting apparatus is pivoted to the gear-case G bysleeve 9, formed upon the rear end thereof, and by a simple pivotedjointat h, the saidjoints being in the line with the crank-shaft. By thisconstruction the vertical swinging of the cutting apparatus on thejoints 9 and h does not disturb the working relation of the crank-shaftM and flywheel m.

The outer end of the cutting apparatus is elevated by theelevating-lever B, which is pivoted to a stud formed upon thegear-casing G, and having the right-angled projection 1', which ispivotally connected with the inner shoe by the link-rod S, theelevating-lever B being held in place by the usual catch-pin, 1"",engaging proper projections formed upon the segment U, which is formedupon the geareasing G. The operation of elevating is shown in Fig. 8,wherein the elevated position of the cutting apparatus is shown bydotted lines.

The cutting apparatus is driven by a drivechain, c, passing over andaround the sprocket-wheel E and sprocket-pinion J, attached to thebcvel-pinion J, which engages and drives the bevel-pinion K, fixed tothe crank-shaft M, upon which is also fixed the ico usual crank-wheel,m, from whose wrist the pitman V is connected to the cutter-bar W,sliding upon the finger bar X, in the usual manner.

The drive-chain e is tightened by the idlepulley Y, pivoted upon thelever Y which is pivoted at its lower end upon the diagonal brace D, andis secured in any desired position by the bolt 3 passing through theslot in a curved projection on the lever Y and into the gear-casing G.

Having thus described the construction, arrangement, and operation of mymachine, and pointed out its new and useful features, what I claim asnew, and desire to secure by Letters Patent, is

1. In a cutting apparatus for a harvestingmachine, a crankshaft, and adriving-gear in engagement therewith located upon and above the innershoe of said cutting apparatus, combined with a lateral coupling arm orbrace pivoted to said shoe on an axis coincident with the center of saidgear, whereby the points of the cutters and guards may be tilted on anaxis coincident with the axis of the driving. gear, substantially as setforth.

2. In a harvesting-machine, the combination of a rigid drag-bar fixed atits rear end to the bracket to which the inner shoe is pivoted'and atits front end pivoted by a suitable movable connection to awhifiietree-bracket, sliding upon the draft-tongue or some fixed partthereof, a diagonal brace pivoted at its front end to the bracket towhich the inner shoe is pivoted, and asupportingbar pivoted at its rearend to the main frame and at its front end to the bracket to which theinner shoe is pivoted, in combination with a cutting apparatus,substantially in the manner shown and described, and for the purposeofenabling the cutting apparatus to freely follow the undulations of theground over which it passes, and by suitable connecting parts to beunder complete control of the operator to raise the inner end of thecutting apparatus independent of the outer end, or the outer endindependent of the inner end, and at the same time V to enable thecutting apparatus to be rocked or rolled in the line of its length.

3. In a harvesting-machine, a whiffietree bracket or plate adapted toslide upon the tongue or some fixed part thereof and having pivoted toit a whifiietree and a tilting-lever, to which in turn is pivoted thefront end of the drag-bar, substantially in the manner shown anddescribed, and for the purpose of forming a direct connection betweenthe whiffietree and cutting apparatus, and at the same time to allow thelatter to be tilted up or down, as may be desired.

4. In a harvesting-machine, the combination of a whiftletree-platesliding on the drafttongue or some fixed part thereof, a drag-barpivotally attached at its front end to said whiffietree-plate, the rearend of said drag-bar being fixed to the bracket to which the cuttingapparatus is pivoted, and a diagonal brace and a supporting-bar, each ofwhich is pivoted atits rear end to the main frame and at its front endto the bracket to which the cutting apparatus is pivoted, substantiallyas shown and described, and for the purpose of flexibly connecting thecutting apparatus with the main frame, yet with the proper degree ofrigidity to withstand the usual strains to which it is subjected.
